This paper presents results of tests on polyurethane to timber joints, made of flexible adhesives, causing reduction of stress concentrations and redistribution of them over larger bonding area. The carried out tests on timber elements, polymers and constructed polymer flexible joints with timber elements resulted in promising ability of the joint to transfer compressive, tensile and shear stresses. Two kinds of polyurethanes of different stiffness were tested statically and cyclically. The obtained results indicate that the tested flexible adhesives can give advantages when are applied in repair of historical timber structures.
